I seem to remember maybe incorrectly, when I was watching an online
example of Domino construction, that the Domino had the ability to cut
some slots marginally wider than the tenons for alignment purposes.

Is that something you considered doing? Or, let me hazard a guess
that it's usually not necessary to use that function because the
Domino is capable of pretty precise cutting and alignment adjustment
is usually not necessary?
